Bug#447156: browser says Unable to bring up wimslogd Permission denied
Hello Boud, I checked every permissions which are set by the package wims at post-install, from revision 3.62-9, they should match with the requirements you list there. I shall try to have this new revision uploaded soon.

ANALYSIS:
From the command line:
as user wims:
cd /var/lib/wims/public_html/ ./wims
outputs a correct html page.
as user www-data, same command:
cd /var/lib/wims/public_html/ ./wims
outputs:
Status: 500 WIMS Internal Error
The command ./wims, in this context, should be executed with the
identity of the user wims, since the post-installation package is
supposed to set the permission bit as stated below:
$ ls -l /var/lib/wims/public_html/wims
-rwsr-sr-x 1 wims wims 266440 2007-10-20 06:16 /var/lib/wims/public_html/wims
The question should rather be : were the permissions correct for the file
/var/lib/wims/public_html/wims ?

gk:~$ grep chmod /var/lib/dpkg/info/wims.postinst
chmod 700 $d
chmod 6755 $server
chown wims:wims $conffile; chmod 600 $conffile
chmod 6755 $lambdawrapper
chmod 6755 /var/lib/wims/public_html/bin/ch..root
gk:~$ grep server= /var/lib/dpkg/info/wims.postinst
server=/var/lib/wims/public_html/wims
webserver=${webserver%,}
webserver=${webserver%,}
---8---
probably the postinst failed at some early stage, but you manually
installed something later and did not run again the configuration scripts?
Amitiés,Georges.

Bug#447156: browser says Unable to bring up wimslogd Permission denied
Hello Boud, the package wims_3.62-8 will be available shortly, which fixes this bug and many others. If you are in a hurry, you can find wims_3.62-7 at an unofficial repository: deb http://debian.ofset.org etch main It appears to have a single bug, which will be fixed in the next release, but this is worked around by making a chown -R wims:wims /var/lib/wims/public_html and making all pending configurations after the failed installation. Best regards, Georges.
